Beading is a cost-conscious way to stiffen ductwork. It is 5 times faster than the old method, cross-braking, and uses only one operator. Designed to meet the requirements of SMACNA, this ductwork prep machine produces 5 beads on 12″ centers and is adjustable to 3/16″ depth. A convenient handwheel raises or lowers, the top roll assembly to set depth of bead. The top and bottom rollers are kept parallel with adjustable screw and pillow block assemblies connected by a link chain. Individual collared beading rolls are replaceable. Feed rolls are self-compensating over the entire gauge range. Double entrance feed bars are provided so that material can be gauged from either left or right side.

Standard with Lockformer quality construction, this machine has a Baldor motor; high precision needle-type bearings; turned, ground, and polished steel forming rolls and roll shafts; and an arc-welded steel stand protected with Lockformer’s top-quality primer and paint finish. Lubrication fittings are located on each bearing.
